I DO understand. I tend to be a perfectionist too, wanting everything to work out RIGHT NOW. But it sounds to me like you are doing everything you can to keep moving forward. Internships can often turn into paid employment, which would be great.

I find it helpful to try and focus on the good in my life, even the little things. I just start listing them off in my head: The sun is shining today. This strawberry I'm eating is absolutely delicious. I did a good job today. I have friends and people who care about me....you get the idea.

Hang in there! Keep doing your best and building a network of people who know you do a good job!
